Title: Improvements in and relating to integrated capacitor memories
IPC: G11C19/18
Filed: 1969-04-23
Abstract: 1,271,154. Active delay lines. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES LTD. 23 April, 1969 [23 April, 1968], No. 20743/69. Heading H3U. [Also in Division H1] An integrated capacitor memory used inter alia for delaying transit times of A.F. and V.F. signals comprises a chain of capacitors between which charge can be transferred via a corresponding chain of transistors in response to control signals applied through their bases, the capacitors being constituted by the collector-base capacitances of the transistors, which are formed in islands on a common substrate. Independent signals can be applied to each transistor (Fig. 1, not shown) to give the maximum delay time per transistor but the number of switching sources can be reduced with only a slight loss of delay time by arranging the transistors in a series of groups (Fig. 6) and applying a common signal to the corresponding transistors in each group, which preferably have a common base region with an N+ underlayer, as in the Fig. 10 structure (not shown), which lacks the final diode D of the Fig. 6 circuit. The circuit operates as described in Specification 1,175,600. In Fig. 10 (not shown) the transistors are of lateral type with the emitter and collector zones formed by diffusion into an epitaxial N-type base layer, which may be contacted at one or several points, on a P-type silicon substrate.

Title: An improved locking device
IPC: H03J1/06
Filed: 1943-12-11
Abstract: 571,379. Pivots. SAY, A. W., MARTIN, R. A., and PLESSEY CO., Ltd. Dec. 11, 1943, No. 20767. [Class 65 (ii)] One or more rotatable drums 1, on spindles 2, are prevented from rotating by bands 3 having lugs 7 on their open ends. The bands are held by pins 5 on a frame 6, and are preferably of varying cross-section so that the bore will remain circular when the band is opened by oppositely-sliding lugs 15 on bars 8, to release the drums. The bars have slots 9 for support pins 11, and are moved in opposite directions by a rotatable cam 12 which is rotated by a hand-knob. Reverse movement of the knob releases the tension on the bands which again grip the drums. A spring 16 may be used to hold the two plates 8 against the cam 12. Means may be provided for indicating when the clamp is engaged or free. Each band preferably has a second moment of area at any point which is proportional to the leading moment at that point.

Title: Aluminium sheet and method of treatment
IPC: C22F1/04
Filed: 1953-07-27
Abstract: 745,411. Making sheets. GARRETT CORPORATION. July 27, 1953 [Aug. 2, 1952], No. 20820/53. Classes 83 (2) and 83 (4). Altering physical structure.-A method of treating an aluminium sheet to inhibit grain growth comprises bending the sheet to deform the skin surfaces of the sheet a greater amount than the material forming the core portion of the sheet. The surface deformations are achieved by successively passing the sheet 17 between rolls 14, 15 and 16. During the first pass the rolls are adjusted as shown in Fig. 3a to deliver the sheet with an upwardly curved bowed configuration to stretch and deform the upper surface of the sheet while causing little or no deformation to the core portion of the sheet. The sheet is then turned over and passed through the rolls adjusted as in Fig. 3b to bow the sheet in the opposite direction and thus stretch and deform the opposite surface of the sheet. Finally, the sheet is passed through the rollers which are adjusted as in Fig. 3c so that the sheet emerges as a flat sheet having workhardened surface layers and an annealed core. The degree of deformation in the sheet surfaces is approximately twenty per cent. Sheets according to the invention may be used for manufacturing heat exchangers, coolers and the like particularly for aircraft.

Abstract: 873,523. Automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 15, 1959 [July 4, 1958], No. 21549/58. Class 40 (4). [Also in Group XL (c)] A circuit for testing the busy or idle condition of an outlet from a switch, comprises a transistor trigger circuit with means for putting a busy condition on the outlet immediately the trigger circuit responds to a free outlet. Fig. 2 shows a selector which may be a group selector or final selector (with or without PBX groups), the requisite line (or group of lines) being marked in the bank M by means of a digit switch DS. The testing circuit TC comprises two transistors VT1, VT2 which are normally non-conducting and conducting respectively. When the P- wiper encounters idle negative battery, the base-emitter circuit of VT1 is forward biased so that the transistor conducts, the consequent rise in collector potential cutting off VT2 by back-biasing its base-emitter circuit. Transistor VT1 when conducting is arranged to draw a much smaller current through resistance R1 than VT2. As a result the emitter potential moves much closer to earth potential. This ensures a rapid change-over of the state of transistor VT1. Moreover, because of the low value of current in R1 the emitter and consequently the base (since VT1 is conducting) are substantially at earth potential and this is applied over wipers DS, M and P to busy the outlet. To set the switch the start relay ST energizes the motor magnet MU and when a free marked outlet is formed and VT2 is cut off, the drop in its collector potential applied to the base of transistor VT3 causes the latter to conduct and operate relay T which inserts the high resistance relay TA into the circuit of MU which releases to stop the switch. Rectifier MR absorbs the energy stored in relay T when the latter is released (by the ultimate opening of st1) so that it does not break down the transistor VT3 in its reverse direction. The invention may also be applied to line finders.
